Before permission is granted, to make a reverse movement, the Dispatcher must determine that?

• A. The train has full crew available.
• B. The block signal is red.
• C. The track is dry.
• D. The track to be used is clear of opposing movements and that blocking devices are applied to protect against opposing movements

Answer: (D)

Before permission is granted for a reverse movement, the Dispatcher must determine that the track to be used is clear of opposing movements and that blocking devices are applied to protect against opposing movements. This is essential because reversing trains can create a collision risk if another train could enter the same track from the opposite direction; having a clear path plus active protection ensures the reversal occurs safely without conflicting traffic. Merely having a full crew, a red block signal, or a dry track does not, by itself, provide the required protection against opposing movements.
